Abstract

Guiasu and Picard [1] introduced the mean length for ‘useful’ codes. They called this length as the ‘useful’ mean length. Longo [2] has proved a noiseless coding theorem for this ‘useful’ mean length. In this paper we will give two generalizations of ‘useful’ mean length. After then the noiseless coding theorems are proved using these two generalizations.
